humidity controller ?

[fandtm666]

I bought this one which seems to work well.

I have this one installed in my setup and works well

top = room temp / relay
middle = humidity sensor / relay
bottom = heater probe temp.

Does this unit accept the standard 110V two prong plug to control the humidifier or do you need to hard wire the powercord into the unit?

OK this seems to be a better product than what I ordered so I've now ordered it. I'll figure out how to wire it once I get it. May attached a 110 female plug to the end using a flat doner extension cord that way I can run the cord through the door seal on the frig.

I'll let you know how it works out and post some pictures.

Ok, so not quite sure why we did not find this link but they indicate that the prices at the on-line store are better than e-bay. I just bought the humidity controller and just finished wiring it up (easy) and setting it up ( a bit more complicated) Seems to be highly accurate. If you are looking for humidity and or temp controllers you should check them out.

Dumb question as I am new to this, but does this humidity controller run both a humidifier and a dehumidifier/fan?

[JerBear]

Depends on the controller. The majority of units can be set for either humidifying or dehumidifying, however, some units can do dual controls.

You'll probably need to ask the ebayer.

Mostly these have a single relay, able to be wired for on/off with both a humidifier (on) and dehumidifier (off), however the wording in the ad seems to state that you can connect either a humidifier or dehumidifier. I'd as k the question to be sure. They don't provide the wiring diagram on the ebay ad, so I can't tell.

[Kaiser Soze]

Just found the wiring diagram and manual here:

http://www.thermomart.com/download/DWH8040.pdf

It seems that you can set either a dehumid or humid mode as follows:

Dehumidification mode: When the measured humidity value is ≥ set value + difference value, relay output is on and when humidity value
is ≤ set value + difference value, relay output is off and disconnected.

Humidification mode: When the measured humidity value is ≤ set value + difference value, relay output is on and when humidity value is ≥
set value + difference value, relay output is off and disconnected.

Bother these modes indicate when the relay is off, it's disconnected.

So I'd say you can only run one or the other.

Still might be wise to ask for clarification.

If you wanted an immediate changeover between humidify/dehumidify, you could use a changeover relay which may save money. I use one for each function as I want a gap between.

I'd be tempted to set things up with the thermostat, and see what happens when you put some products to dry in there, before spending money on hygrostats.

Fandtm666,
If you don't mind, I would like to pick your brains for some advise. I noticed your coolroom with airconditioner.
I will be building a smallish coolroom/curing chamber 6x7x7 ft with the smallest window airconditioner as cooling.
Being in the Sub tropics here, the airco might switch on more frequently and case harden all my salamis, coppa's etc.
A forum member suggested to have a seperate section all curtained off by some heavy industrial plastic see through sheeting to stop this.
Makes lots od sense to a novice like me.
I also prefer all seperate controllers.
Any thoughts on the above info.
Thank you,
Jan.

I know a few of us have used the heavy plastic tarps to keep humidity up but not sure how much something non-insulated would do to retain cool air in an otherwise warm space.

[crustyo44]

Eric,
The curtaining-off set up will be in the coolroom itself. The temperature in the coolroom will be set for drying meat/salamis etc with the humidity the same.
Where the curtain comes in is to stop the breeze from the Airco blowing on them to stop case hardening.
No doubt I will have to experiment and probably have a humidty meter inside the curtained of area.
Cheers,
Jan.

Sorry it has taken a while for me to reply have been flat out with work and family issues.

To limit the chance of case hardening i have put a flap in front of the aircon so that the air is blown onto the roof area and then drops down to the floor so it is constantly circulating and as such it is not blowing directly on the salami etc.

As for the humidity i also have a large tub of water sitting in the middle of the coolroom which i change out every other day and thus far it has worked well keeping the humidity level at around the 80%.

I also noticed you are in Brisbane so the conditions where i am are pretty similar as i am in tweed heads

[Kaiser Soze]

Do you change out the water to stop it becoming manky? I would assume a big tub of salt water would be fine to sit there for weeks without growing anything?

Probably because im a little over cautious and it only takes a couple minutes to do so

Fandtm666,
We will have to get together one day and discuss a few things over a couple of cold beers.
You seem to have the coolroom/curing chamber problems worked out very well.
Cheers Mate,
Jan.
